Hot melt adhesive coating machine unwinding mechanism capable of continuously receiving materials

Abstract

The invention relates to the technical field of coating machines, and discloses a hot melt adhesive coating machine unwinding mechanism capable of continuously receiving materials. The hot melt adhesive coating machine unwinding mechanism comprises a support, a reinforcing seat is arranged at the upper end of the support, a mounting plate is arranged on the surface of the reinforcing seat, a transverse plate is arranged at the side end of the mounting plate close to the joint of the support, a supporting pipe is arranged at the side end, close to the transverse plate, of the upper end of the reinforcing seat, movable seats are arranged on the surfaces of the transverse plate and the supporting pipe, optical shafts are arranged on the inner sides of the movable seats, sensors are arranged at the lower ends of the movable seats, and clamping mechanisms are arranged at the upper end of the transverse plate. The hot melt adhesive coating machine unwinding mechanism capable of continuouslyreceiving materials has the advantages that the whole unwinding mechanism is convenient to disassemble and maintain; the tension of a base film in the unwinding process can be adjusted conveniently, and the coating effect of the base film can be improved; and a real-time monitoring function is achieved, position deviation of the base film in the unwinding process can be corrected in time, and thecoating quality of the base film is improved.

Description

technical field [0001] The invention relates to the field of coating machines, in particular to an unwinding mechanism of a hot melt adhesive coating machine capable of continuous feeding. Background technique [0002] Hot melt adhesive coating machine is a kind of polymer that does not need solvent, does not contain water, and is 100% solid meltable. It is solid at room temperature, and it is heated and melted to a certain extent to become fluid and viscous. Liquid adhesive, coated on the substrate, usually includes a composite part, which can compound another substrate and the coated substrate; it does not require drying equipment, low energy consumption, and does not contain solvents (The hot-melt adhesive is 100% solid content) No pollution, the operator will not be exposed to a large amount of formaldehyde due to cleaning the remaining glue, compared with the traditional solvent-based and water-soluble adhesives, professionally manufactured hot-melt adhesives The coati...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an unwinding mechanism of a hot melt adhesive coating machine capable of continuous splicing, which is equipped with the entire unwinding mechanism for easy disassembly and maintenance; it is convenient for adjusting the tension of the base film during the unwinding process , which is conducive to improving the coating effect of the base film; with the real-time monitoring function, it can correct the position deviation of the base film in the unwinding process in time, improve the coating quality of the base film, and solve the problem of the traditional unwinding mechanism. It is easy to disassemble, which leads to inconvenient maintenance; it is inconvenient to adjust the tension of the base film during the unwinding process, which affects the coating effect of the base film; it does not have the real-time monitoring function, and cannot correct the position deviation of the base film in the unwinding process in time, which affects the base film.
